I'm selling this because I found it while organizing my home. I believe the green cassette is Rockman 5, but I can't confirm it, so I've priced it based on the market value of 4 and 6, adding a little extra. I don't have a console or environment to test it, so I can't guarantee it works. Therefore, I've listed it as "poor condition overall." Please check the photos for the condition of the item. I apologize, but no claims or returns are accepted. Thank you for your understanding.
